grouding conductor

[jbernardo]

Does the grounding conductor for parking lot pole lights and ballfield pole lights have to be sized the same as the feeder conductors?

 

[augie47]

Size per 250.122 Note that if the current carrying conductors are increased in size the EGC must be proportionally increased.

 

[don_resqcapt19]

The EGC has to be the same size as the ungrounded conductors if the OCPD is 30 amps or less.

I agree with the others and here is the code section

250.122 Size of Equipment Grounding Conductors.

(B) Increased in Size. Where ungrounded conductors are
increased in size, equipment grounding conductors, where
installed, shall be increased in size proportionately according
to the circular mil area of the ungrounded conductors.
